·Combustion Air Required AquaStar 125FX
In order to ensure an adequate supply of combustion air, the
National Fuel Gas Code requires that any conventional vented gas appliance be
installed in a room with a minimum volume of 50 cubic feet per 1,000 Btu/hr
rated input. The following is the minimum size of the open space in which the
AquaStar Tankless Water Heater Model 125FX may be installed in compliance
with this requirement:
| Model |
Volume |
Area with an 8' ceiling |
| 125 FX |
5,900 cubic feet |
738 square feet |
If the AquaStar Hot Water Heater is installed in an area smaller than indicated
above, then the installer must make special provisions for combustion air in the
form of two openings, each one within 12" of the top and 12" of the bottom of
the space, having a total free area of 1 square inch per 1,000 Btu/hr of rated
input if the air is taken from inside the house. This requirement reduces to 1
square inch per 4,000 Btu/hr if the air is taken from the outside.
Note: This calculation assumes normal rates of
"infiltration" of outside air. A super-insulated, super-tight space/building may
require outside air for the AquaStar Water Heater even though the volume/area of the space
meets this application.
Caution: In addition to the above, the AquaStar Gas Hot Water Heater must be
properly vented to ensure safe and efficient operation.
